Boost.Build doesn't have a way to cache
that information. It would be pretty
difficult to implement.

You could use:
project mylib ;
if --track-all-dependencies in [ modules.peek : ARGV ]
alias mylib : ... ;
seached-lib mylib : ... ;
One issue is that this requires the libraries to
be installed to some standard location. It would
take more work to get it to use the libraries directly
from the build tree.
